Coarse solids retention

In channels where combined sewage and storm water are conveyed, there are also some coarse substances, such as grit and sewage related debris. These coarse substances usually move more slowly than the water flow and often cause problems with downstream plant and equipment. In principle the goal is to identify the sources of grit or debris entering the sewerage system and eliminate them to prevent sewage related debris within the sewer system.
